Wow, 15 replies in 3 hours...now that's impressive!
I don't have that problem at my field, but I've seen it at other places many times such as Joe Nall. I can see that point of the original post. Bob Sadler made a point to reinforce the hovering needed to stay on the opposite side of the runway and the guys quickly obliged.
One question comes to mind...if you're torque rolling over the runway, how do you deal with emergency situations such as someone deadstick? Presuming you can hear the "deadstick" call over the hovering plane's engine, the deadstick plane can be on the ground in short order. I know from personal experience that I've yelled "deadstick" and had the plane down in just a few seconds due to it happening at low altitude. Could be ugly...
I'm not a 3D-er, but I don't hold anything against them...personally, I've become fascinated with some of the things that Quique did with AA, but of course much of his demo at Joe Nall was very close to the flight line as well.
